Nuclear DNA damage has detrimental effects on cellular homoeostasis and accelerates the ageing process. A new study causally links error-prone mitochondrial replication to increased nuclear DNA damage, thus suggesting that the hallmarks of ageing are associated with nuclear genome instability, a potential unifying denominator in the ageing process.
